Khali and Juan are using ribbon to decorate their art project. The ratio of the length of Khali’s ribbon to the length of Juan’s ribbon is 8:5. If Khali used a total of 72 cm of ribbon, how much did Juan use?

45 cm

Step-by-step explanation:

First, you want to clarify the ratio:

Khali    =    8 cm   =     72 cm

Juan     =    5 cm   =      x cm

To find the missing variable, cross multiply and simplify for x:

8x = 72(5)

8x = 360

x = 45

So, Juan used 45 cm of ribbon if Khali used 72 cm.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
